The girl filed the petition for child support in Chicago, claiming Keef — real name Keith Cozart – fathered a baby daughter with her back in 2011.

The girl’s exact age is unclear, but according to the docs, she currently attends a Chicago middle school — meaning she was .. at MOST … in 8th grade when she conceived the child, but could have been in 6th grade.

Cozart — who has since worked with Kanye West, Young Jeezy, and Rick Ross — was 15 at the time.

The crazier part about this story is that in the state of Illinois, it’s illegal for 2 people under the age of 17 to have sex, whether consensual or not. It’s a misdemeanor, but it’s unlikely charges will be filed. The girl wants money for child support, health insurance, and medical expenses.

Keef had a daughter when he was 16, and he put the child support papers on Instagram. So if this is his baby, maybe he’ll handle his business…?

I’m lilD, and that’s the Word Eye Heard. Young girls, make better decisions. Have you seen his face?!?!?!
